It's higly higroscopic, moreover braider cords are like sponges. Now I use monofilament nylon rope, like fishing line, some 3 mm in diameter but it's impossible to knot, you must use steel clamps. For end insulator polycarbonate is not higroscopic and selfextinguish (correct?) it can be worked like metal and can be bended up to 90 degree using bending machine. You can test polycarbonate using a lighter, perspex and polystirene burns polycarbonate not. 73 de Claudio, IK2PII ---------------------------------------------------------------------- Claudio Pozzi http://www.qsl.net/ik2pii happy Linux user E-Mail: Claudio Pozzi Date: 31-Oct-02 Time: 17:57:09 This message was sent by XFMail ----------------------------------------------------------------------
